Portable Network Graphics (PNG) stands for graphics files that can be a replacement for GIF files. The main difference between GIF and PNG files is that PNG doesn’t support animations. Since PNG files use lossless compression, they are often used to store graphics on websites. Lossless compression means that the original data can be saved after compression, in other words, your file will be of the same quality even though its size was reduced.
PNG files don’t work well on the older versions of Internet Explorer, especially version from 4 to 8. However, PNG works well on Safari, Mozilla, Opera and Chrome. Given that PNG files can be used on all operating systems, there is usually a default program for viewing such files. For instance, you can use default Microsoft Photo Viewer or Microsoft Windows Photos to open png files in Windows. You can view png files on Mac and Linux as well. Google Drive also supports png files, so you can access them from your phone or a tablet too.
Even though PNG files have a lot of advantages, such files are not suitable for every task. In some situations, other formats, such as PDF work better. Luckily, there is a way to convert files from PNG to PDF and switch between file formats based on your needs.
